From 991f2ec0e8a2668cfe80feb33ec2bc5189c973b4 Mon Sep 17 00:00:00 2001 From: Edward Smyth Date: Mon, 3 Oct 2022 10:55:49 +0000 Subject: [PATCH] BLIS: Errors in Netlib LAPACK Tests Zen4 kernel bli_damaxv_zen_int_avx512 is causing incorrect results in the netlib LAPACK tests, specifically in: ./xlintstd < ../dtest.in > dtest.out in the TESTING/LIN directory. Given time constraints, i.e. the need to finalize code for AOCL 4.0 release, disable calls to AVX512 kernel (i.e. always use the AVX2 kernel) for now, and aim to correct bli_damaxv_zen_int_avx512 for AOCL 4.1.
